Diesel engines also tend to last longer and require less maintenance than petrol engines.
Diesel engines are typically heavier and noisier than petrol engines. This is because diesel engines use compression to ignite the fuel, which creates more noise than a petrol engine. Petrol engines, on the other hand, use spark plugs to ignite the fuel, which is much quieter.
The design of German and Japanese engines also differs. German engines tend to be more complex and powerful, while Japanese engines are simpler and more efficient. German engines are usually more expensive to maintain, as they require more complex parts and regular servicing. Japanese engines, on the other hand, are usually cheaper to maintain and require less frequent servicing.
When it comes to performance, German engines are generally more powerful and can reach higher speeds. Japanese engines, however, are usually more efficient and provide better fuel economy.
In terms of emissions, German engines are usually more polluting than Japanese engines. This is because diesel engines produce more carbon dioxide and other pollutants than petrol engines.
Overall, German and Japanese engines have their own advantages and disadvantages. German engines are generally more powerful and expensive to maintain, while Japanese engines are usually more efficient and cheaper to maintain. It is important to consider all of these factors when deciding which type of engine is best for your car.
